'Bones' first look: Brennan musters a smile for Hannah's big entrance

Hold on to your butts. What could potentially be the most divisive plot move in
"Bones" six seasons makes its formal debut on the Sept. 30 episode, "The Couple in the Cave." And for all the speculated drama, everyone sure looks happy.

We're speaking, of course, of Hannah Burley (
Katheryn Winnick), the war correspondent who won the heart of Seeley Booth (
David Boreanaz) during his seven-month tour in Afghanistan.

The season premiere delved little into the Hannah issue, but episode 2 makes up for lost time. What begins with Brennan's (
Emily Deschanel) minor interrogation of Booth's emotional investment in his new relationship -- she's just trying to learn, people -- soon segues into the first appearance of Hannah herself. Cue the awkward intro!

Seriously though, after just a few seconds, it's pretty obvious what Booth sees in her. So don't tune in expecting a villain.

Naturally, the following clip is of the spoiler-ish variety, but if you're at all curious to see this new love triangle's first scene together, you may want to throw caution to the wind.
